"My plumbers and machinists like using the Slip-ON Lock Nut.
The plumbers use them to install refrigerators and sinks in areas
with limited access. They simply slide the nut on the anchor mount,
turn it to the locked position, run it down tight, and twist an
additional 1/4-turn to secure the units being installed. The machinists
use them where excess bolt length and insufficient space restricts
torquing the nut with a socket. They also find them very useful
as quick-change positioning stops on shop equipment as well as reducing
setup time."

Harry
Armstrong from Griffiss AFB, New York,
said, " the Slip-ON Lock Nut is a godsend. My people use them
to install cable ladders, ducts, and trays during major upgrades
of telecommunications installations. Work that [formerly] took hours
has been reduced to minutes because there is no longer a requirement
to disassemble existing fixtures or equipment. My people requested
using these nuts for all applications; however, the cost to replace
standard nuts for all applications could not be justified, although
they are being used for new projects and major facility upgrades.
The savings on a $250,000 upgrade project amounts to thousands of
dollars. In addition to the labor and material savings on retrofit
projects, there is the added benefit of speeding up completion time
which makes for a smooth transition with less disruption in day-to-day
operations, than is normally associated with retrofit and major
construction projects."

The
Detroit Testing Laboratory
also tested and proved the effectiveness of the Slip-ON Lock Nut
thread system using a standard commercial rod and grade-8 bolts
to evaluate clamp load and tensile strength. The test results revealed
that a 1/2-inch-13UNC Slip-ON Lock Nut could be tightened to 95
foot-lbs. Of torque without failure, could provide clamp loads as
high as 14,950 lbs., and could withstand tensile stress loadings
as high as 103,000 psi without failure. (Note: A 1/2-inch commercial
grade rod, with a safety factor of 5, has recommended clamp load
of 1,130 lbs.)
